Formula: Enchant Weapon - Battlemaster
Is a World Drop from high level mobs (66-70). There has been much debate on this enchant on how it is best used. Some melee dps players have tried as well as tanks. The proc will heal everyone in the "party", which would mean only the 5 people/pets in your group, (not whole raid) and only those within 30 yards. The general belief is that the healing proc generates threat as a healing spell like any other heal, but threat meters do not conclusively confirm it. Consensus has not been reached on battlemaster's threat generation. If it does cause threat, for endgame it is negligible even if the entire party is healed. (A good proc heal is equivalent threat to an average attack or heal at level 70 in poor gear.)
Proc rate is 1 PPM melee only. Unlike most other enchants, battlemaster does not proc more often from ability use or mainhand use. Nothing a player does or equips seems to increase the PPM.* It either cannot proc from instant attacks (ie procs from autoattack only), or can only proc on white damage attacks. This makes the enchant better suited for an offhand weapon if dual wielding.
It can crit heal. Spelldamage gear seems to benefit the heal slightly. Unlike most heals, this is not holy, but classed as an arcane effect.
*Choices a player makes can decrease the PPM however.
(note: the following is this author's test results of Battlemaster)
After enchanting (1.6 speed)with Battlemaster, I went and farmed primals from Voidspawns in Nagrand, Elementals in Nagrand, and also various other high level mobs. Other than the Voidspawns, all mobs were level 70-72. According to ProcMeter, Battlemaster procced approx 1.5% out of 4342 attacks with a 3.92% miss rate (I know I need more +hit!). Assuming a tank has ~0.0% miss, Battlemaster should proc around 1.5-1.75% of the time with a 3.5 speed weapon.
Edit 2: With further testing Battlemaster procced 1.80% with a 1.64% miss rate (2261 total attacks).
